MEANS FOR CONTROLLING THE CASTERING OF THE FURRO W-WHEELS OF FLOWS.

To. all whom izimag concern Be it known that I, WILLIAM H. LEE, ofSyracuse, in the county of Onondaga and State of New York, have inventeda certain new and useful Means for Controlling the Castering of theFurrow-VVheels of Plows, of which the following is a specifica. tion.

particularly to means for controlling the castering ofthe rear furrowvwheel; and it consists in the coinbinationsand constructions hereinafterset forth and claimed.

In describing this invention reference is had to the accompanyingdrawing in which corresponding I like characters designate parts in allthe views.

Figure 1 is a plan, partly broken away, of

the plow having no bearing on this inven tion, being omitted. Figs. 2and 3 are views similar to Fig. 1, illustrating the positions a plowembodying my invention, parts of the plow is turning, respectively, tothe this plow comprises afframe 1' supported by front, and rear furrowwheelsQ and 3 andv by the usual land wheel, not shown, and connectionsbetween the front and rear furrow wheels whereby the rear wheel, is,normally held from castering out of the furrow upon the land, when theplow is traveling in a straight line, and is free tocaster during theturning of the plow in ,eitherdirection, so thatit will remain in thefurrow. during the turning of theplow.

The land wheel, the earth turning element, and :parts appurtenantthereto, may beof any desirable form, size and construction and as theyform no part of this invention, and as their construction is well known,de scription and illustration thereof is thought to be unnecessary.

The frame 1 may be of any desirable form, size and construction, and ishere shown as formed with a laterally-extending member f at its frontend, having an up 5 in which is journaled anupright spindle 6 providedon the axle of the front furrow wheel 2. The tongue 7, or

other membercontrolling the direction of the line of draft, is connectedto the upright spindle 6 in order to turn the front wheel 2 during theturning of the plow at Specification of Letters Patent. Applicationfiled August 26,1910,

a corner. The front furrow wheel isQhere shown as on the left side oftheplow frame, but may be located on the right side ifthe earth turningelement turns a right hand furrow. The, rear furrow orcaster wheel 3turns on an inclined axle/8, so that the wheel is staggered in the usualmanner. Said axle is carried at the rear end of the forwardly extendingsupporting member 9 wh ch'terminates in an upright spindle 1O ournaIedinthe vertical bearing 11 associand here illustrated ated with theframe,

a bracket 12extendas formed atthe end of ing rearwardly from the frame1..

The connection between the, front and rear furrow wheels 2 and 3,comprises rock arms 13 and114 mounted, respectively, upon the splndles 6and 10 and extending laterally therefrom; and a rod 15 connecting. therock arms, the rod 15 having sliding or yielding connectionwith both ofsaid arms. Said rod ismovable at its front endtoward and from the axisof said arm 13 and is from its normal position relatively to the rearvrock arm 14. As shown, these rock arms extend in opposite arm 13 is pro16, in which: slides a member 17 pivoted to the front end of the rod 15;and-the rear arm 14 is provided with a swiveled eye 18 through which therod 15 extends The eye is capable of sliding on the rod, rearwardly fromits nor mal positionand the rod is capable of sliding in;the eyeforwardlyfrom its normal position. vForward movement of the eye-from itsnormal] position, Fig. 1, on the rod, is:

rod 15 andengaging the front side-of said eye, so that the rear furrowwheel is held or in its position asin its normal position,

prevented by shoulder 19 .provided; onthe sumedgflwhen the plow istraveling .in a straight line, saidshoulder 19 being preferablyadjustable along the rod 15,

' The frontrock arm 13 inclinesforwardly from the spindle 6 when theplow is traveling in a straight, line, so that its end is in front of astraight line, passing through the axis of the spindle 6 andperpendicular to the normal line of draft, and, during the turning ofthe plow to the left',said arm 13 moves forwardlyintothe position shownin Fig. 3. The rod 15is'normally prevented" from movement by the forwardpushing of the arm 14:, due to'the tendency of said rear i furrow wheelto caster, by the fact that the member 17 is at the outer end of theslot 16 in the front arm 13 and said member 17 is in front of a straightline passing through the axis. of the spindle 6 and perpendicular duringthe turnihgof the plow and will not be controlled in its movement by thefront wheel. During the turning of the plow to theiright," Fig. 2, therock arm 13 swings rearwardly until the end thereof is in rear l of aline passing through the axis of the spindle .6 and perpendicular to thenormal line of draft, so that the member 17 owing,

to the engagement of the shoulder 19 and eye '18, and to the tendency ofthe wheel 3 to caster, will slidelengthwise of the slot 16 of the wheel3is to caster such direction that the 'arm114 moves away fromth'e'shoul-- der '19. Obviously owing to the sliding connections of therod 15 with the front and rear rock arms 13 and 14-, the rear furrowwheel will be normally held from 'caste'ring and white free to casterinthe right directiongto facilitate the turning of the plow whether theplow is turning to the right or left, sothat saidfrear furrow wheel willremain in the furrow an'd will not be forced out of the furrow duringthe turning of the plow. fQwing to the arrangement of the front arm 13'and the bearing 17 of the rod 15 at the'endof the slot'16 farthestremoved from the axis of such" arm, the rod 15 is instantly releasedfrom holding force when the tongue '17 begins to turn from itspositionjshown 'in Fig.1 toward that shownin Fig. When the plow isagaintra'veling in a straight "line after turning'a corner to the left,theinember 17 is. again moyed to the outer ,en'do f the slot 16bythefor'ward push- .ing of the rockarm 14. I-t'w ill be understood thatowing to the staggerin o'f th'e furrow wheel 8 the 'wlieel'has atendency to either follow in a straight gline or turn out.

of the furrow in one direction, and such tendency to mo-ve'out of thefurrow is normally resisted by the shoulder 19, and that owing to therod and arms 13, 1 1, when the plow turns in one direction as to theright, as shown in Fig. 2, the furrow wheel. is-free to turn toward theleft or the plowed land, owing to the fact that the arm 1 1 is free tomove rea'rwardly while the frame of r the plow is turning, and furtherthat when turning to the-left, as seen in Fig. v3, the

shoulder 19 is pulled away from the eye 18 direction lengthwise of theaxis of the rod,

the rod also having a bearing slidable along the front :arm toward andfrom the axis right spindle journaledin the front hearing, a v I 1 arearwheelprovided with-an uprig it spindle ournaled in the rear bearing,rock jarins on the spindles and extending laterally in I oppositedirections from their spindles, the toward the spindle 6.
